帝国CMS 列表模板list.var支持程序代码，cmslist.var

1、增加模板时list.var模板需要勾选“使用程序代码”选项。如图：

2、直接添加PHP代码，不需要加程序开始和结束标记。

3、字段值数组变量为$r，对应的字段变量为$r[字段名]，如：标题字段变量就是$r[title]。另外编号变量为$no

4、将最终模板内容赋给$listtemp变量。

例子1：如果信息没有设置标题图片就显示指定的图片。

https://www.gxlcms.com/<span>1</span> https://www.gxlcms.com/<span>if(empty($r[titlepic]))
</span>https://www.gxlcms.com/<span>2</span> https://www.gxlcms.com/<span>{
</span>https://www.gxlcms.com/<span>3</span> https://www.gxlcms.com/<span>        $r[titlepic]='/images/img.gif';
</span>https://www.gxlcms.com/<span>4</span> https://www.gxlcms.com/<span>}
</span>https://www.gxlcms.com/<span>5</span> $listtemp='https://www.gxlcms.com/<span><</span>https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>><</span>https://www.gxlcms.com/<span>a </span>https://www.gxlcms.com/<span>href</span>https://www.gxlcms.com/<span>="[!--titleurl--]"</span>https://www.gxlcms.com/<span>><</span>https://www.gxlcms.com/<span>img </span>https://www.gxlcms.com/<span>src</span>https://www.gxlcms.com/<span>="[!--titlepic--]"</span>https://www.gxlcms.com/<span>><!--</span-->https://www.gxlcms.com/<span>a</span>https://www.gxlcms.com/<span>><!--</span-->https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>></span>';</span></span>

说明：$r[titlepic]为标题图片字段变量。$listtemp为模板内容变量。

例子2：如果信息是今天发布的就显示“NEW”图片标识。

https://www.gxlcms.com/<span>1</span> https://www.gxlcms.com/<span>$newimg='';
</span>https://www.gxlcms.com/<span>2</span> if(time()-$r[newstime]https://www.gxlcms.com/<span><</span>https://www.gxlcms.com/<span>=1</span>https://www.gxlcms.com/<span>*24*3600)
</span>https://www.gxlcms.com/<span>3</span> https://www.gxlcms.com/<span>{
</span>https://www.gxlcms.com/<span>4</span> https://www.gxlcms.com/<span>        $newimg</span>https://www.gxlcms.com/<span>='<img <="" span="">https://www.gxlcms.com/<span>src</span>https://www.gxlcms.com/<span>="NEW图片地址"</span>https://www.gxlcms.com/<span> border</span>https://www.gxlcms.com/<span>="0"</span>https://www.gxlcms.com/<span>></span>https://www.gxlcms.com/<span>';
</span>https://www.gxlcms.com/<span>5</span> https://www.gxlcms.com/<span>}
</span>https://www.gxlcms.com/<span>6</span> $listtemp='https://www.gxlcms.com/<span><</span>https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>><</span>https://www.gxlcms.com/<span>a </span>https://www.gxlcms.com/<span>href</span>https://www.gxlcms.com/<span>="[!--titleurl--]"</span>https://www.gxlcms.com/<span>></span>[!--title--]https://www.gxlcms.com/<span><!--</span-->https://www.gxlcms.com/<span>a</span>https://www.gxlcms.com/<span>></span> '.$newimg.'https://www.gxlcms.com/<span><!--</span-->https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>></span>';</span></span></span>

说明：$r[newstime]为发布时间字段变量。$listtemp为模板内容变量。

例子3：调用投稿用户的公司名称。

https://www.gxlcms.com/<span>1</span> https://www.gxlcms.com/<span>$userr=$empire->fetch1("select company from {$dbtbpre}enewsmemberadd where userid='$r[userid]' limit 1");
</span>https://www.gxlcms.com/<span>2</span> $listtemp='https://www.gxlcms.com/<span><</span>https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>><</span>https://www.gxlcms.com/<span>a </span>https://www.gxlcms.com/<span>href</span>https://www.gxlcms.com/<span>="[!--titleurl--]"</span>https://www.gxlcms.com/<span>></span>[!--title--]https://www.gxlcms.com/<span><!--</span-->https://www.gxlcms.com/<span>a</span>https://www.gxlcms.com/<span>></span> https://www.gxlcms.com/<span><</span>https://www.gxlcms.com/<span>span</span>https://www.gxlcms.com/<span>></span>公司名称：'.$userr[company].'https://www.gxlcms.com/<span><!--</span-->https://www.gxlcms.com/<span>span</span>https://www.gxlcms.com/<span>><!--</span-->https://www.gxlcms.com/<span>li</span>https://www.gxlcms.com/<span>></span>';</span></span></span>

说明：$r[userid]为发布者用户ID字段变量。$listtemp为模板内容变量。

https://www.gxlcms.com/其他说明：
如果$listtemp引用模板内容是用单引号，那么里面使用单引号前面要加\，例如：$listtemp='\'[!--titlepic--]https://www.gxlcms.com/\'>';
相反如果引用模板内容是用双引号，那么里面使用双引号前面也要加\，例如：$listtemp="\"[!--titlepic--]https://www.gxlcms.com/\">";

支持程序代码可以实现很多非常复杂的应用需求。
